i have a 408 that will be daily driven and have the **** pounded out of it on the street and prob every week or too at the track, car will be shifted at 6600 and my clearances are between 28 and 30 . i have a 7.5 quart pan with 2 -10an fittings so ill be running a remote filter, mostlikley far from the pan... and also a oil cooler. my engine builder suggests not using a hi volume.. what should it do!!!!

thank you, adam

Melling 10296 is what I would use

Melling 10295 is what I use. It has 75psi @ idle when cold and about 65-70 @ idle when hot. This is on a stock 2007 LQ4 shortblock with 5W-30 oil.

10295 is a favorite here. Its a high pressure standard volume unit.

Get a different engine builder lol.

With a remote filter, oil cooler, and clearances that big, you're going to want some thing like a Melling 10355. It's their VVT/DOD version oil pump with a higher volume than the 10296.

A 10296 pump would probably work too, but you're likely going to see really low oil pressure at idle with a 10295.

Kind of off topic, would the 10296 be okay for a street car or the 10295 even if it's just a heads/cam SBE car?

Either one would be fine. I'd lean towards the 10295 though for a SBE.

He said it will starve the pan

If you have 65 at idle hot what is it Gina be at 7,000rpm? That scares me

And with thos clearances come thicker oil, I'll be running 15 40 at least

Engine builder says ported but not hi volum

That's funny because I run a 10296 (high volume) and I never starved my oil pan. I know of several others running the 10355, which is even higher volume, and they haven't had any issues either.

I run a ported VVT/DOD GM pump by Synergy. I run 60 PSI hot idle. It builds to about 75 over 5000.

I like this pump: http://stores.precisionoilpumps.com/...ume-race-pump/

Ok apparently he didnt know i had a 7.5qaurt pan even tho i told him.. i may didtch the oil cooler for now but still need the remote oil filter, just so happend i have a overkill one that was laying around and my cousin gave it to me, it uses a 2q fillter... and prob another 1/2 q in the lines... so that puts me at 10 quarts of 15/40 lol... ok if your 75 at 5k.. whats it gonna be at 7... and what oil do you run... also how do these hi volume pumps work? Do they actually have a diffrent drive or bigger casting? Or are they just ported pumps falsely claimed as hi volum? Because a stock pan i would assume would def be dry at 7k with a hi volume

This one def gets my attention... it even comes saftey wired! Lol i wonder why no companys ever tell you the actuall gpm.. i dont really want over 80 psi at full rev

And i should note my engine guy has never done anything ls..mabey thats part of the diffrences of opinions here?

I run 10W30 VR1.

I have that pump in my motor. It wasn't safety-wired, I suppose that's an option?

I did a cranking speed test to check for leaks and pressure:
